Need anyone’s with this apex question! much appreciated to anyone!

The correct answer option is D. (1 - 0.2)s.

Step-by-step explanation:

We are given that a store is offering 20% off all shoes. Rosalie purchases shoes and clothes.

Assuming s to be the cost of shoes.

After the discount, the cost of shoes will be s minus 20% of s so we can write an equation:

After factoring out s, we get:

\text{The cost of shoes after discount}=(1-0.2)s

Therefore, option D. (1 - 0.2)s is the correct one.
